[UK-CONTEST] What switched mode 13.8V PSU?

[James Fisher]

I am looking for some recommendations on a 13.8V switched mode PSU for operating portable and holidays with my K2.
I have seen several on the market from:
Astron
Watson
SEC
Diamond.

Any thoughts? Or other makes I should consider?
I guess a multi input voltage unit 115/230 or similar would be more flexible than a 230 only

Also I have heard reports that some switched mode PSUs can suffer problems when connected to a generator that runs out of fuel and the waveform lengthens from the std 50Hz resulting in PSU failure. Does anyone have any inputs on this or should I just heave along the bigger heavier linear supply?
